Part I 8.00% per annum ------------- Amount invested =x
\n" ); document.write( "Part II 2.00% per annum ------------ Amount invested = y
\n" ); document.write( " 2200
\n" ); document.write( "Interest----- 104.00
\n" ); document.write( "
\n" ); document.write( "Part I 8.00% per annum ---x
\n" ); document.write( "Part II 2.00% per annum ---y
\n" ); document.write( "Total investment
\n" ); document.write( "x + 1 y= 2200 -------------1
\n" ); document.write( "Interest on both investments
\n" ); document.write( "8.00% x + 2.00% y= 104
\n" ); document.write( "Multiply by 100
\n" ); document.write( "8 x + 2 y= 10400.00 --------2
\n" ); document.write( "Multiply (1) by -8
\n" ); document.write( "we get
\n" ); document.write( "-8 x -8 y= -17600.00
\n" ); document.write( "Add this to (2)
\n" ); document.write( "0 x -6 y= -7200
\n" ); document.write( "divide by -6
\n" ); document.write( " y = 1200
\n" ); document.write( "Part I 8.00% $ 1000
\n" ); document.write( "Part II 2.00% $ 1200
\n" ); document.write( "
\n" ); document.write( "CHECK
\n" ); document.write( "1000 --------- 8.00% ------- 80.00
\n" ); document.write( "1200 ------------- 2.00% ------- 24.00
\n" ); document.write( "Total -------------------- 104.00
